In the world of skincare, there are several hardworking ingredients that get very little attention but can be vital to the performance of a skincare product. Glycerin is one such ingredient! Refined glycerin’s uses in skincare are numerous, but first, what is glycerin? What is Glycerin? Glycerin is a natural component of healthy skin. It’s also known as…

Resins of industrial products, It often contains excess solvents, monomers and oligomers produced by incomplete reactions. 1.According to the capacity of exchange column, the resin was weighed according to the mass ratio (cation: anion = 1:2) and put into open barrels separately. The resin was immersed in 98% medicinal alcohol for 5-10 cm and 24…

The synthesis of glycerol from propylene can be classified into two categories: chlorination and oxidation. Propylene chlorination and propylene peracetic acid oxidation are still used in industry. 2.1 Propylene oxidation This is the most important method to synthesize glycerol, which includes four steps: oxidation of propylene to propylene chloride at high temperature, hypochloritization of…

It mainly comes from the by-products of soap production and oil cracking: before 1948, glycerol was completely recovered from the by-products of animal and vegetable oil soap production. Up to now, natural oils and fats are still the main raw materials for glycerol production. About 42% of natural glycerol comes from by-products of soap making…

The boiling point of glycerin at atmospheric pressure is 290 ℃, and at 204 ℃ it begins to decompose and polymerize, so crude glycerol distillation needs to be carried out under decompression. For example, under the pressure of 20mmHg, the boiling point of glycerol is 181.34℃, and it is 116.11 ℃ at 10mmHg pressure. In order to further…

The purity of glycerol determines the value of glycerol, the higher the purity of glycerol the higher the market value for glycerol. Glycerol refinement will help biodiesel plants turn into a stronger profit with its refined glycerol’s since it cost less than fully refined grade. The refined grade greens the business as its takes less…

The global increase in biodiesel production has led to a marked increase in world glycerin production. Glycerin is produced as an approximately 11 percent byproduct in the transesterification of triglycerides, which are the predominant feedstock material for producing biodiesel. Glycerin remains one of the most versatile and valuable known chemicals and has a wide variety…

This process above can be either continuous or batch mode. The process consists of five separation steps: first reactor, second reactor, decanter, flash distillation column, and adsorption column. This new process to be able to produce glycerol higher than 99.5% purity from typical crude glycerol. First reactor: The crude glycerol is preheated first before heading…
